kiddush Hashem is assessed by how the torah and HKBH view something that happens. Why would Hashem be happy that one of his children is singing with a bunch of goyim in las vegas. do you think it would make R chaim kanievsky happy? and isnt he close to Hashem? So it would follow that he would understand what makes Hashem happy? why in the world do some people lket what they think and what their emotions tell them get in the way of how yiddishkeit view something? Kiddush Hashem isnt toluy on what your gut says, nor is it toluy on what you want to be true. so can it.
